A critical measurement in selecting which oil line kit will work for your turbo is
the oil drain flange. By measuring the mounting bolt holes of your drain flange
from center to center you can obtain this measurement. Standard drain flange
measurements are 38mm, 44mm, and 50.8mm. In rare occurances there are
other sized drain flanges. By ordering the next smallest size and opening up
the mounting holes on the drain flange you can mount a drain flange on any turbo.
